If 0.1mV≤ Vp<5mV, ±1%±1LSB. Current6A (24bit A/D) Ip accuracy(before stacking)If Ip≥ 5mA, ± 0.2% ±1LSB;If 0.1mA≤ Ip<5mA, then ± 1% ±1LSB.. Apparent Polarizability Accuracy±1% ±1LSBBefore the project is carried out, it is necessary to find out the fault distribution in the working area. At present, 2D high density electrical method is mainly used for detection, and 3D high density electrical method is added for comparative analysis. In order to verify the effectiveness of 2D and 3D high-density electrical method in detecting faults and understand the response characteristics of faults, forward and reverse fault models were established. Forward modeling by finite element method and least square inversion were used to compare the differences of inversion results between different models. Finally, field examples were used for further analysis and verification. The results show that the high density electrical method is effective and accurate in detecting faults, but the detection effect of the reverse fault is obviously better than that of the normal fault. The 3D high density electrical method has abundant data and large inversion depth, and the results are closer to the theoretical model. The field measured data further verify the simulation results, and the conclusions obtained have certain guiding significance for fault detection, interpretation and analysis
